Mini Pinball Is All-pixels

October 6, 2010 by Mike Szczys 20 Comments

You won’t find those familiar steel balls inside this mini-pinball cabinet. That’s because [Luis’] latest creation is a fun way to play virtual pinball. The playing field is a 10″ LCD screen with an accompanying 8″ screen in the marquee. Inside the well-crafted case you’ll find a mini-ITX motherboard running HyperPin, a frontend software suite for LCD-based virtual pinball. He’s also using PinMame for the score board that was often provided by a gas plasma display on newer mechanical machines. There’s video after the break, and take a moment to check out [Luis’] other mini-cabinet builds.

What’s that you say? No substitute for the real thing? That’s exactly what [Ben Heck] thinks too.

Launchpad Takes Ultra Low Power To The Extreme

September 30, 2010 by Jakob Griffith 62 Comments

We’ve all known the MSP430s under the Launchpad are designed to be low power, but who wants to bet how long the chip can last on only 20F worth of capacitors? A couple of hours? A day at max? [Kenneth Finnegan] setup a MSP430 with supercaps to find out. To make sure the chip is actually running, [Kenneth] programmed it to count from 0 to 9 over a period of 10 seconds, and then reset. To get it ultra low power, the chip is in sleep mode most of the time, and a raw low current LCD is used to display the output. While [Kenneth] simply checks the chip every few hours to see if it’s still counting, a setup much like the Flash Destroyer, tracking a clock and then storing the current value would get a more exact time of death. Either way, it’s been over 3 weeks…and still counting. Video after the rift.

Digital View-Master

August 24, 2010 by Mike Szczys 27 Comments

Who could forget the stereoscopic goodness of a View-Master? [Tuttle] put a modern flair on the classic optical device by adding two 1.5″ LCD screens. The screens replace the film disk of the original, showing slightly different images to produce a 3D effect. No word on a camera rig used to take the original images, but for our money this a great way to make something out of those useless key chain picture frames.

PIC Based Picture Frame

July 19, 2010 by Mike Szczys 29 Comments

Take a PIC 24HJ256GP206 processor and add a dash of knock-off touchscreen and a pinch of SD card compatibility for a DIY digital picture frame. [Daniel] wrote his own driver for the HX8347 controlled LCD that can achieve 15 FPS at 320×240 resolution with 16-bit color. As this was a gift for his wife, [Daniel] included a heart-shaped ring of LEDs that fade in and out like an electronic pulse. He notes that the JPEG decoder runs rather slow but that’s mostly because of the bottleneck caused when accessing data from the SD card. We’ve got more pictures and a link to the source code after the break.

Chess Table: Physical Interface For Internet Games

July 11, 2010 by Mike Szczys 15 Comments

Wanting to get back to playing with actual pieces, [Thomas Pototschnig] built a chess table that interfaces with the Internet. The table uses an custom setup to project the board on the frosted surface of the table. Chess moves from your internet opponent are displayed as arrows on the board so you can move the pieces. Your moves are detected by a webcam below the surface as this table actually functions as a multitouch display. From the description, it sounds like the projector was made from a 128×64 graphic LCD display. A 64×64 pixel area is used, with an LED below and a lens above. This works remarkably well. See for yourself after the break.

Want some other options for your chess setup? You can play against a robot arm, or if you’ve got 144 square feet of extra space you can build a really big board for the occasional game.

Connecting A Nokia 3310 LCD Using An AVR

July 6, 2010 by Caleb Kraft 7 Comments

In this instructible, [wkter] takes us through the process of running a Nokia 3310 LCD display using an ATmega8. This instructible isn’t a beginners project as he assumes you already have a strong understanding of how to work with these components and their programming languages. He is very thorough with information though, providing datasheets, pinout diagrams, and source code. Once you get this down, you could go a little further and make Conway’s game of life.

Hijacking The Mazda LCD Display

April 16, 2010 by Mike Szczys 75 Comments

[Pieter] is in the process of adding a turbo package to his ride. He needed a status display for the boost but didn’t have a good way to mount an additional display. He came up with the idea of using the LCD screen that’s already in the dashboard, but the specs for it were not available. Wielding his hard-earned hacking skills [Pieter] used a logic analyzer to sniff out the communications to the screen. He built a controller board that overrides the data coming in from the head unit. The board is also able to query the car’s computer for data and display it in any format you want. What he ends up with is a stock look that he can customize for his needs. Nice!
